Inv ardor DAVID PHILANDER BIGAELOV, OF ARLVILLE, IOVA.

SPECIFICATIONforming part of Letters Patent No. 378,650, dated February28, 1888.

Application filed June i8, 1887.

I0 @ZZ whom it may concern.-

Be it known that I, DAVID PHILANDER Bref- ELOW, a citizen of the UnitedStates, residing at Earlville, in the county of Delaware and State ofIowa, have invented certain new and useful Improvements in Nail-Hammers,and I do declare the following to he a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon,which form a part of this specification.

Thespecial object ofthe invention is to make a hammer adapted to drivelarge orsmall nails without slipping thereon; also, to do blind-nailing;also, to prevent the hammer'handle from working loose in the head orbeing slivered; also, to render end of hammer perfectly tight in thehead.

Figure l of the drawings is a longitudinal section showing the handle,head, and auxiliary parts put together; Fig. 2, a detail view, in sideelevation, of the handle; Fig. 3, a perspective view of the top strap 5Fig. 4, a similar view of the bottom strap; Fig. 5, a similar view ofthe tightening-wedge.

In the drawings, A represents the handle having the rabhets a a onopposite sides, the shoulders a a', and the open end slots, a2 a2.

B is the upper fastening-strap, and C the lower one, both made of metaland each hav ing a front shoulder. These front shoulders, Z) c, rest inthe front notches, d d', of the hammer D.

On the top strap, B, there is no rear shoulder 5 but on the bottom one7C, is the rear shoul- Serial No. 241,763. (No model.)

der, c2, which fits in the rear notch, d2, ot' the hammer-head.

The wedge E is made with the side shoulders, c, so that when driven intothe handle slots aKZ the wood that has been pressed out laterally willspring back over the shoulders e and effectually prevent the wedge frombeingjarred out.

In practice I fit the bottom strap, C, into the head with its shoulder'c in the notch d and the shoulder c in the notch d2, then put the handlein, and drive the top strap into the head until the shoulder b entersthe hemmen notch d. Finally, I drive the wedges E horne7 into the openslots a2, when the hammer is com plete and ready for use.

I make the hammer-head to weigh from one and one-half to two pounds, andmake the workingface d3 perfectly flat, so that it will not slip on anail.

Having thus described all that is necessary to a full understanding ofmy invention, what I claim as new, and desire to protect by LettersPatent, is

The combination of a wooden handle having open end slots, a2, metallicstraps B C, having shoulders b c ci, a hammer head having the notches dd di, and the wedges E E, having shoulders e @,wherehy the shoulders I)c c2 may be forced into and held in the notches d d di, as described.

In testimony whereof I affix my signature in presence of two Witnesses.
